ll. 5ll0, and it may he kept for a August 21, 187 3- .To all! who: it may con-corn:

Be it known that I, ltiiynonn (L /mun, of Toulouse, Department of the ilaute-(laronne, in the Republic of lirai-iee, have invented a new Miningddndfi, and which serves at the same time for the cure of the phyloxera \'as-- tat-rix, of which the following is a specification: p l

l The raw materials serving for the manulac: ture of one hundred kilograms of my pow der are as follows: Nitrate of potash, or nitrate of soda, or nitrate oi lime, from iil'ty to sixty kilograms, (which can he used inmixed proportions or separately sulphur, from thirteen to sixteen kilograms; tanners bark, coming out of i-he pits containing remains of animals, or sawdust, from fourteen to sixteen kilograms, (can he used mixed or separately) soot or lamp-black, from nine to eighteen kilo grams, (can he used mixed or separately;) water, the necessary quantity, and from live to six kilograms of sulphate of iron per hundred kilograms of a mixture of the abovementioned ingredients.

The preparation 01" this compound is as follows: in order to facilitate the reactions-l pulverize the raw material by means oi a millstoue, and then place them in a boiler much larger than would be sullieient to inst hold the materials on account of the swelling ol' the materials during the reaction. I then add the sulphated water in' quantity sul'iicient to moisten the materials in the boiler, and heat the whole to between 110 and 120 Fahrenheit, at which point the materials become entirely liquid, and the reactions take place, and when the solid is deposited or formed it is taken oil the lire and dried at a high temperature.

.111 this state the compound is a solid sub stance, of the form oi a more or less fine powder, of a blackish color, and oi a density of very long time without undergoing the least alteration or deterioration. Its purity amigreater or less dynamical force depend upon ihe mrity of the raw materials employed and thernroportions adopted for its mannlacture.

In the atmospheric air it takes lire andburns like any other inflammable body upon bhe contact of any ignited nod-3", or of a some of sullicicnt intensity, without the least shock or the least explosion, whatever may be the quantity of malerials submitted to the test. Neither almospherie electricity, a high tom peratureot the :llluosphcle, nor shocks of any kind have any action upon this substance. But when this compound is firmly compressed in the hole of a mine and then lighted it ex- -plo les, and produces by the quantity, and especially by the nature, of the g: ses proceed ing from the combustion, a dynamical cll'eet superior (at equal weights used) to the ordinary mining-po\vder, and equal to that of dynamite used in trade, the low price of this compound givingit a great udvantage ovcr other minirig-powders.

This ei'nnpouud is without danger in its manufacture, its keeping, on its use, and it am he lighted like the ordinary mining-powder by means of a mining-fuse. It produces in its explosion much less smoke than the common powder, and the gas it; emits does not injure the health'ot' the miners, as is the case in dynamite; and in the mine-hole, al'terjits explosion, there is no trace even left of a solid deposit.

This substance, as it is ignited with much dilliculty in the atmosphere, and as it docs not detonate without being compressed, may be stored in all inhabited places with perfect safety.

l eig 1 ,1 )loy the sulphate of ll.r|l to prevent the combustion of the. composition at a low temperaturc, and thus materially insure the safety of its use, as from 2,000 to moon-01' limiternecessary to piodue ignition. I

This substance, being lincly triturated and dissolved in water in the primal-Lion of two kilograms for one hundred liters oi wa-ier, produces a very good result in the destruction of the phyloxera vast-atrir'c.

New, having described my invention, what I claim isi A mining-powder composed of nitrate oi potash, sulphur, manncrs hark, lamp-black, water, and sulphate oi iron, substantially as described.
